The clip is basically talking about Senator McCain who responded to a concerned woman by implying that “Arab” and
“Good-person” cannot coexist as features of a single human being.
Now listen to it the second time but this time focus on the audience response.
The first 25 seconds: the audience dont seem to understand what why the sentence “he is not an Arab, he is a good man” is absurd or funny.
Second 25 to second 30: the speaker now substitutes the word “Arab” with “Jew” and now the audience see the absurdity in the statement.
I can’t see the audience so I can’t tell their response by looking at them but based on the audio, it makes you wonder how many people unconsciously equate Arab = Bad in their heads; it had to be that for one paying attention not to see the absurdity in the statement until it is expounded.
